Heating Performance

Microcomputer-controlled Automatic Defrosting

This air conditioner operates on the heat-pump principle, absorbing heat from outdoor air and transferring that heat indoors.

As a result, the operating performance is reduced as outdoor air temperature drops. If you feel that insufficient heating

perfomance is being produced, we recommend you use this air conditioner in conjunction with another kind of heating

appliance.

Heat-pump air conditioners heat your entire room by recirculating air throughout the room, with the result that some time

may be required after first starting the air conditioner until the room is heated.

When using the Heating mode under conditions of low outdoor air temperature high humidity, frost may form on the

outdoor unit, resulting in reduced operating performance.

In order to prevent this kind of reduced performance, this unit is equipped with a Microcomputer-controlled Automatic

Defrosting function. If frost forms, the air conditioner will temporarily stop, and the defrosting circuit will operate briefly

(for about 7 to 15 minutes).

Clean the air filter

Pull the filters upward to remove them from the Intake Grill.

Clean the air filter: Remove the dust from the filters by vacuum cleaner or washing

them. After washing, allow the air filters to dry thoroughly in an area protected from

sunlight.

Re-attach the air filters to the Intake Grill. Press the two buttons on the filters until

you hear a sound of click.

12

Maintenance

When used for extended periods, the unit may accumulate dirt inside, which reduces its performance. We recommend

that the unit is inspected regularly, in addition to your own cleaning and care. For more information, consult authorized

service personnel.

When cleaning the unit's body, do not use water hotter than 40 C, harsh abrasive cleansers, or volatile agents like

benzene or thinner.

Do not expose the unit body to liquid insecticides or hairsprays.

When shutting down the unit for one month or more, first allow the Fan mode to operate continuously for about half a

day to allow internal parts to dry thoroughly.

Troubleshooting

Followings are not problems

Sound of water flowing is not a problem.

Sound of cracking is heard.

Smell are generated.

During operation, white fog or steam

comes out from the indoor unit.

No outlet air or fan speed can't be changed

in dry mode.

In cooling operation, unit switches to

blowing operation.

Won't start?

In heating operation, water or steam

are blown out of outdoor unit.

In heating operation, indoor fan won't stop

even if unit is stopped.

During unit operation or at stop, a swishing or gurgling noise may be heard.

This noise is generated by refrigerant flowing in the system.

Unit will not restart after stop.

During unit operation, a cracking noise may be heard.

This noise is generated by the casing expanding or shrinking because of

temperature changes.

This is because the system circulates smells from the interior air such as

the smell of cigarettes or the painting on the furniture.

When unit is running at places like restaurant, etc. where dense edible oil

fumes always exist, this will happen.

To prevent frost from accumulating on indoor heat exchanger, unit will switch

to blowing operation for a while then resume cooling operation.

Though ON/OFF button is set to ON, the unit won't

resume cooling, dry or heating operation in 3 min

after it is stopped, this is because of

3-min-delay protection circuit.

Please wait 3 minutes

Unit will reduce fan speed repeatedly and automatically if room temp. is

too low in dry operation.

This occurs when frost accumulated on the outdoor unit is removed.

(during defrosting operation)

After unit stop, indoor fan will go on running until indoor unit cools down.

14

Troubleshooting

Before ask for services, please first check your unit against the following.

If your unit still can't work properly after above mentioned checks, or following problems occur, please stop it immediately

and contact your dealer.

Fuses or circuit breakers often blow out.

Water comes out in cooling/dry operation.

Operation is abnormal or sound is heard.

Air conditioner won't start.

Poor cooling or heating
